MOSCOW (Sputnik) — According to the Today’s Zaman newspaper, the attack was carried out in the Nusaybin district of the southeastern Turkish province of Mardin.
The newspaper added that the explosive device detonated when a police bus passed through Nusaybin.
Tensions in Turkey escalated in July 2015, after 33 Kurdish activists were killed in a suicide blast in the town of Suruc on the border with Syria and two Turkish policemen were later murdered by PKK, which led to Ankara's military campaign against the group.
Turkish President Recep Tayyip Erdogan said in his New Year’s statement that Turkish security forces had killed 3,100 PKK militants in 2015.
